Public Utilities Commission

Target: Less than 2.11% of median income 

Result: 1.27% of median income

This measure represents service affordability of water and wastewater services provided by the San Francisco Public Utilities Commission (SFPUC) to San Francisco residents. The SFPUC is committed to providing water and wastewater at an affordable rate to its customers. Measuring water and sewer rates in relation to median income in San Francisco is one indication of affordability.

The Sewer System Improvement Program (SSIP), SFPUC’s 20-year, multi-billion dollar investment in upgrading the city’s aging sewer infrastructure so that it is seismically safe and reliable, includes specific goals and levels of service that the SFPUC has set to guide project selection and evaluate program implementation. One such goal is to maintain ratepayer affordability, and the SFPUC has pledged to keep customer bills less than 2.5 percent of an average household income for a single-family home throughout the multi-phased SSIP implementation. In the Fiscal Year 2016-17, the target is to keep customer bills less than 2.11 percent. This level of service goal applies to Water and Wastewater, as historically these are the services provided to residents of San Francisco by the SFPUC.



How the Public Utilities Commission is Performing

SFPUC’s rates are generally on par with its peers and lower than the affordability criteria established by the U.S. Environmental Protection Agency (EPA). Utility bills reflect the cost of SFPUC’s efforts maintain assets in good working order, encourage conservation, and cover costs associated with the extraction, treatment, distribution, and delivery of water, as well as the treatment and disposal of wastewater, and delivery of power. Rates are set four years at a time.

In fiscal year 2014-15, customers conserved water due to the drought and voluntary 10 percent reduction implemented by SFPUC. The average monthly volume of water used by single family customers decreased from 6 centum cubic feet (ccf) to 5.4 ccf. As a result, water and wastewater bills have decreased compared to target percentages.

How Performance is Measured

This measure is determined by calculating the annual average household bill. Median income comes from the City and County of San Francisco’s Comprehensive Annual Financial Report (CAFR) and is adjusted for inflation. Figures are calculated for 1) Water, Wastewater individually, and 2) combined Water and Wastewater.
